44d8fe9646 Don't abort InnoDB/XtraDB if one can't allocate resources for AIO
- Better error messages

This fixes that one again can run the test systems with many threads without having to increase fs.aio-max-nr.


mysql-test/include/mtr_check.sql:
  Ignore the INNODB_USE_NATIVE_AIO variable (may change during execution)
mysql-test/mysql-test-run.pl:
  Ignore warnings for failure to setup AIO
storage/innobase/os/os0file.c:
  Continue without AIO even if we can't allocate resources for AIO

164080e4a8 WL#6161 Integrating with InnoDB codebase in MySQL 5.5
Changes in the InnoDB codebase required to compile and
integrate the MEB codebase with MySQL 5.5.

@ storage/innobase/btr/btr0btr.c
  Excluded buffer pool usage from MEB build.
 
  buf_pool_from_bpage calls are in buf0buf.ic, and
  the buffer pool functions from that file are
  disabled in MEB.
@ storage/innobase/buf/buf0buf.c
  Disabling more buffer pool functions unused in MEB.
@ storage/innobase/dict/dict0dict.c
  Disabling dict_ind_free that is unused in MEB.
@ storage/innobase/dict/dict0mem.c
  The include

  #include "ha_prototypes.h"

  Was causing conflicts with definitions in my_global.h

  Linking C executable mysqlbackup
  libinnodb.a(dict0mem.c.o): In function `dict_mem_foreign_table_name_lookup_set':
  dict0mem.c:(.text+0x91c): undefined reference to `innobase_get_lower_case_table_names'

  make[2]: *** [mysqlbackup] Error 1

  innobase_get_lower_case_table_names
  innobase_casedn_str
  are functions that are part of ha_innodb.cc that is not part of the build
        
  dict_mem_foreign_table_name_lookup_set
  function is not there in the current codebase, meaning we do not use it in MEB.
@ storage/innobase/fil/fil0fil.c
  The srv_fast_shutdown variable is declared in
  srv0srv.c that is not compiled in the
  mysqlbackup codebase.

  This throws an undeclared error.

  From the Manual
  ---------------

  innodb_fast_shutdown
  --------------------

  The InnoDB shutdown mode. The default value is 1
  as of MySQL 3.23.50, which causes a “fast� shutdown
  (the normal type of shutdown). If the value is 0,
  InnoDB does a full purge and an insert buffer merge
  before a shutdown. These operations can take minutes,
  or even hours in extreme cases. If the value is 1,
  InnoDB skips these operations at shutdown.

  This ideally does not matter from mysqlbackup

a28a2ca798 Bug #13933132: [ERROR] GOT ERROR -1 WHEN READING TABLE APPEARED
WHEN KILLING

Suppose there is a query waiting for a lock.  If the user kills
this query, then "Got error -1 when reading table" error message
must not be logged in the server log file.  Since this is a user
requested interruption, no spurious error message must be logged
in the server log.  This patch will remove the error message from
the log.

    message:
      Bug#13417754 ASSERT IN ROW_DROP_DATABASE_FOR_MYSQL DURING DROP SCHEMA
      
      This assert could be triggered if an InnoDB table was being moved
      to a different database using ALTER TABLE ... RENAME, while this
      database concurrently was being dropped by DROP DATABASE.
      
      The reason for the problem was that no metadata lock was taken
      on the target database by ALTER TABLE ... RENAME.
      DROP DATABASE was therefore not blocked and could remove
      the database while ALTER TABLE ... RENAME was executing. This
      could cause the assert in InnoDB to be triggered.
      
      This patch fixes the problem by taking a IX metadata lock on
      the target database before ALTER TABLE ... RENAME starts
      moving a table to a different database.
      
      Note that this problem did not occur with RENAME TABLE which
      already takes the correct metadata locks.
      
      Also note that this patch slightly changes the behavior of
      ALTER TABLE ... RENAME. Before, the statement would abort and
      return an error if a lock on the target table name could not
      be taken immediately. With this patch, ALTER TABLE ... RENAME
      will instead block and wait until the lock can be taken 
      (or until we get a lock timeout). This also means that it is
      possible to get ER_LOCK_DEADLOCK errors in this situation
      since we allow ALTER TABLE ... RENAME to wait and not just
      abort immediately.

The following scenario crashes our mysql server:

1.  set global innodb_file_per_table=1;
2.  create table t1(c1 int) engine=innodb;
3.  alter table t1 discard tablespace;
4.  alter table t1 add unique index(c1);

Step 4 crashes the server.  This patch introduces a check on discarded
tablespace to avoid the crash.

6b05e434bf Bug #13955256: KEYCACHE CRASHES, CORRUPTIONS/HANGS WITH,
FULLTEXT INDEX AND CONCURRENT DML.

Problem Statement:
------------------
1) Create a table with FT index.
2) Enable concurrent inserts.
3) In multiple threads do below operations repeatedly
   a) truncate table
   b) insert into table ....
   c) select ... match .. against .. non-boolean/boolean mode

After some time we could observe two different assert core dumps

Analysis:
--------
1)assert core dump at key_read_cache():
Two select threads operating in-parallel on same key 
root block.
1st select thread block->status is set to BLOCK_ERROR 
because the my_pread() in read_block() is returning '0'. 
Truncate table made the index file size as 1024 and pread 
was asked to get the block of count bytes(1024 bytes) 
from offset of 1024 which it cannot read since its 
"end of file" and retuning '0' setting 
"my_errno= HA_ERR_FILE_TOO_SHORT" and the key_file_length, 
key_root[0] is same i.e. 1024. Since block status has BLOCK_ERROR 
the 1st select thread enter into the free_block() and will 
be under wait on conditional mutex by making status as 
BLOCK_REASSIGNED and goes for wait_on_readers(). Other select 
thread will also work on the same block and sees the status as 
BLOCK_ERROR and enters into free_block(), checks for BLOCK_REASSIGNED 
and asserting the server.

2)assert core dump at key_write_cache():
One select thread and One insert thread.
Select thread gets the unlocks the 'keycache->cache_lock', 
which allows other threads to continue and gets the pread() 
return value as'0'(please see the explanation above) and 
tries to get the lock on 'keycache->cache_lock' and waits 
there for the lock.
Insert thread requests for the block, block will be assigned 
from the hash list and makes the page_status as 
'PAGE_WAIT_TO_BE_READ' and goes for the read_block(), waits 
in the queue since there are some other threads performing 
reads on the same block.
Select thread which was waiting for the 'keycache->cache_lock' 
mutex in the read_block() will continue after getting the my_pread() 
value as '0' and sets the block status as BLOCK_ERROR and goes to 
the free_block() and go to the wait_for_readers().
Now the insert thread will awake and continues. and checks 
block->status as not BLOCK_READ and it asserts.  

Fix:
---
In the full text code, multiple readers of index file is not guarded. 
Hence added below below code in _ft2_search() and walk_and_match().

to lock the key_root I have used below code in _ft2_search()
 if (info->s->concurrent_insert)
    mysql_rwlock_rdlock(&share->key_root_lock[0]);

and to unlock 
 if (info->s->concurrent_insert)
   mysql_rwlock_unlock(&share->key_root_lock[0]);

storage/myisam/ft_boolean_search.c:
  Since its a recursion function, to avoid confusion in taking and 
  releasing the locks, renamed _ft2_search() to _ft2_search_internal() 
  function. And _ft2_search() will take the lock, call 
  _ft2_search_internal() and release the lock in case of concurrent 
  inserts.

7a6c449c62 Bug #13943231: ALTER TABLE AFTER DISCARD MAY CRASH THE SERVER
The following scenario crashes our mysql server:

1.  set global innodb_file_per_table=1;
2.  create table t1(c1 int) engine=innodb;
3.  alter table t1 discard tablespace;
4.  alter table t1 add unique index(c1);

Step 4 crashes the server.  This patch introduces a check on discarded
tablespace to avoid the crash.

0e9c1e9fc3 Bug #13955256: KEYCACHE CRASHES, CORRUPTIONS/HANGS WITH,
FULLTEXT INDEX AND CONCURRENT DML.

Problem Statement:
------------------
1) Create a table with FT index.
2) Enable concurrent inserts.
3) In multiple threads do below operations repeatedly
   a) truncate table
   b) insert into table ....
   c) select ... match .. against .. non-boolean/boolean mode

After some time we could observe two different assert core dumps

Analysis:
--------
1)assert core dump at key_read_cache():
Two select threads operating in-parallel on same key 
root block.
1st select thread block->status is set to BLOCK_ERROR 
because the my_pread() in read_block() is returning '0'. 
Truncate table made the index file size as 1024 and pread 
was asked to get the block of count bytes(1024 bytes) 
from offset of 1024 which it cannot read since its 
"end of file" and retuning '0' setting 
"my_errno= HA_ERR_FILE_TOO_SHORT" and the key_file_length, 
key_root[0] is same i.e. 1024. Since block status has BLOCK_ERROR 
the 1st select thread enter into the free_block() and will 
be under wait on conditional mutex by making status as 
BLOCK_REASSIGNED and goes for wait_on_readers(). Other select 
thread will also work on the same block and sees the status as 
BLOCK_ERROR and enters into free_block(), checks for BLOCK_REASSIGNED 
and asserting the server.

2)assert core dump at key_write_cache():
One select thread and One insert thread.
Select thread gets the unlocks the 'keycache->cache_lock', 
which allows other threads to continue and gets the pread() 
return value as'0'(please see the explanation above) and 
tries to get the lock on 'keycache->cache_lock' and waits 
there for the lock.
Insert thread requests for the block, block will be assigned 
from the hash list and makes the page_status as 
'PAGE_WAIT_TO_BE_READ' and goes for the read_block(), waits 
in the queue since there are some other threads performing 
reads on the same block.
Select thread which was waiting for the 'keycache->cache_lock' 
mutex in the read_block() will continue after getting the my_pread() 
value as '0' and sets the block status as BLOCK_ERROR and goes to 
the free_block() and go to the wait_for_readers().
Now the insert thread will awake and continues. and checks 
block->status as not BLOCK_READ and it asserts.  

Fix:
---
In the full text code, multiple readers of index file is not guarded. 
Hence added below below code in _ft2_search() and walk_and_match().

to lock the key_root I have used below code in _ft2_search()
 if (info->s->concurrent_insert)
    mysql_rwlock_rdlock(&share->key_root_lock[0]);

and to unlock 
 if (info->s->concurrent_insert)
   mysql_rwlock_unlock(&share->key_root_lock[0]);

storage/myisam/ft_boolean_search.c:
  Since its a recursion function, to avoid confusion in taking and 
  releasing the locks, renamed _ft2_search() to _ft2_search_internal() 
  function. And _ft2_search() will take the lock, call 
  _ft2_search_internal() and release the lock in case of concurrent 
  inserts.

d4d3ca204f Fixed lp:997460 Truncate table on partitioned Aria table fails with ER_ILLEGAL_HA
Fix is done by doing an autocommit in truncate table inside Aria

storage/maria/ha_maria.cc:
  Force a commit for TRUNCATE TABLE inside lock tables
  Check that we don't call TRUNCATE with concurrent inserts going on.
  Make ha_maria::implict_commit faster when we don't have Aria tables in the transaction.
  (Most of the patch is just re-indentation because I removed an if level)

391ea219c2 Bug #14007649 65111: INNODB SOMETIMES FAILS TO UPDATE ROWS INSERTED
BY A CONCURRENT TRANSACTIO

The member function QUICK_RANGE_SELECT::init_ror_merged_scan() performs
a table handler clone. Innodb does not provide a clone operation.  
The ha_innobase::clone() is not there. The handler::clone() does not 
take care of the ha_innobase->prebuilt->select_lock_type.  Because of 
this what happens is that for one index we do a locking read, and 
for the other index we were doing a non-locking (consistent) read. 
The patch introduces ha_innobase::clone() member function.  
It is implemented similar to ha_myisam::clone().  It calls the 
base class handler::clone() and then does any additional operation 
required.  I am setting the ha_innobase->prebuilt->select_lock_type 
correctly.
